‘Diamond Rouge’ is a stunning new variety of Hydrangea paniculata, known for having the reddest flowers of all its types. In early summer, it starts with large white flower heads that slowly change through shades of pink as the season goes on. By early autumn, these flowers turn into beautiful red hues. This sun-loving Hydrangea is perfect for modern gardens, offering vibrant color with minimal care. ‘Diamond Rouge’ is especially great for smaller gardens, as it grows to about 1.5 meters tall. It’s earned worldwide recognition for its striking color, hardiness, and easy maintenance.
